MatrixORTHOGNATHIC Plating System. Specialized implants and instruments for orthognathic surgery.

The aim of surgical fracture treatment is to reconstruct thebony anatomy and restore its function. According to the AO, internal fixation is distinguished by anatomical reduction,stable fixation, preservation of blood supply, and early, activemobilization.1,2 Plate and screw osteosynthesis has been established and clinically recognized for some time.

Keeping the AO philosophy at its core, Matrix is the newplating platform for internal fixation of the craniomaxillofacialskeleton–addressing neuro, craniofacial, mandibular, and orthognathic surgery. Matrix is a simple, yet comprehensive,system that offers flexibility and ease of use.

Simple– All screws work with all plates within each Matrix system– One screwdriver for all screws within each Matrix system– Color-coding by strength for easy identification

Effective– Low plate-screw profile, where applicable– Self-retaining screws/blades– Rounded edges on plates

Efficient– Standardized instrumentation– Reduced inventory for hospitals, without

compromising clinical solutions

AO Principles

Synthes 7

In 1958, the AO formulated four basic principles, which havebecome the guidelines for internal fixation.3,4 They are:

Anatomic reductionFracture reduction and fixation to restore anatomical relationships. A comprehensive implant and instrument selection offers the ability to address most simple and complex fixation needs.

Stable fixationStability by rigid fixation (compression plating) or splintage,as the personality of the fracture and the injury requires.The MatrixORTHOGNATHIC plate and screw system is optimized to achieve stable bone fixation.

Preservation of blood supplyPreservation of the blood supply to soft tissue and bone bycareful handling and gentle reduction techniques.

Early mobilizationEarly and safe mobilization of the part and patient. TheMatrixORTHOGNATHIC system implants, combined with AO technique, provide stable fixation enough to allow afunctional aftercare.

The Synthes MatrixORTHOGNATHIC Plating System is intendedfor use in selective trauma of the midface and craniofacialskeleton, craniofacial surgery, reconstructive procedures, and selective orthognathic surgery of the maxilla, mandibleand chin in adolescents* (greater than 12 to 21 years of age)and adults.

Specific Indications for Use:– Fractures of the midface and craniofacial skeleton– LeFort I osteotomies, sagittal split osteotomies and

genioplasties– Orthognathic surgery including reconstructive procedures

* Important considerations in achieving quality outcomes fororthognathic surgery in growing patients include accurate diagnosis, proper treatment planning and appropriate agesequencing of procedures.5

Surgical Technique

1Select plate design

After the osteotomy has been performed and the new position of the maxilla has been established, select the plateshape and thickness that best suits the bony anatomy, treatment objective and quantity and quality of bone.

Oblique L-plates, 90° L-plates, and I-plates are recommendedfor both medial and lateral buttress fixation.

Pre-bent maxillary plates are recommended for medial buttress fixation.

Anatomic L-plates are recommended for lateral buttress fixation.

03.503.035 In-plane Plate Bender for Midface Plates

03.503.038 Plate Bender for Midface Plates (2 required)

03.503.039 Plate Cutter for Midface Plates

Cut and contour the plate according to the bending templateand the bony anatomy using the Plate Cutters (03.503.039)and the Plate Benders (03.503.038, 03.503.035) respectively.Bend the plate between the holes as necessary. Ensure theplate is passively adapted to the bone.

Notes:

– Etched lines, in 1 mm increments, to facilitate bendingand placement.

– Do not alter the bend in the pre-bent plates to achieve more than a 1 mm adjustment in either direction.

Cautions: – Confirm that plate positioning, drill bit length, and screw

length allow for adequate clearance of nerves, tooth budsand/or tooth roots, and the edge of the bone.

– Do not excessively bend the plates as it may produce internal stresses which may become the focal point foreventual breakage of the implant.

– Damage to developing tooth roots may result in dento-osseous ankylosis and localized dentoalveolar growth impairment.6

4Fixate plate to bone

Insert proper length 1.85 mm Matrix Screws to fixate theplate to the underlying bone.

If pilot hole is desired, select the appropriate 1.4 mm diameterdrill bit length to allow for the adequate clearance of nerves,tooth buds and/or tooth roots.

Caution: Drill rate should never exceed 1800 RPM. Higherrates can result in thermal generated necrosis of the boneand an oversized hole to be drilled. The detriments of anoversized hole include reduced pullout force, increased easeof screws stripping in bone, and/or suboptimal fixation. Always irrigate during drilling.

Notes:

– Self-drilling and self-tapping screw are available.– Use at least two screws on each side of the osteotomy to

achieve stable fixation.

Straight and curved sagittal split plates are available formonocortical screw placement.

The Sagittal Split Plate with Adjustable Slider is also availableif intraoperative occlusal adjustments are necessary (see page 15 for technique).

Notes:

– For bicortical screw placement, 1.85 mm diameter Matrixscrews are available in lengths up to 18 mm (positionscrews). Predrill using 1.4 mm diameter drill bit withoutstop.

– The 10 mm to 18 mm length screws have a larger head diameter for better visibility and force transmission.

4Primary plate fixation

Select the appropriate 1.4 mm drill bit length to allow for theadequate clearance of nerves, tooth buds and/or tooth roots.

Fixate the Sagittal Split Plate with Adjustable Slider to thebone by drilling and inserting the proper length 1.85 mm Matrix Screws in the specified sequence as shown (1–3) (Figure 1). Screws should be placed monocortically.



– Drill rate should never exceed 1800 RPM. Higher rates canresult in thermal generated necrosis of the bone and anoversized hole to be drilled. The detriments of an over-sized hole include reduced pullout force, increased ease of screws stripping in bone, and/or suboptimal fixation. Always irrigate during drilling.

5Operative correction of occlusion

Release the intermaxillary fixation and inspect the occlusion.If the occlusion needs adjustment, loosen the screw (3) in the slider plate (Figure 2).

The distal bone segment can now be shifted horizontally and vertically until the occlusion has been corrected.

Retighten the screw (3) in the slider.

The process can be repeated if necessary.

Note: Ensure the desired condylar positioning has beenachieved.

6Final plate fixation

Using the 1.4 mm diameter drill bit to drill, insert the remain-ing proper length 1.85 mm Matrix Screws in holes (4) and (5)(Figure 3).

Remove the screw (3) and the slider plate component. Ensurefixation of the mandible is adequate to withstand the sagittalforces.

Cautions: – Drill rate should never exceed 1800 RPM. Higher rates can

result in thermal generated necrosis of the bone and anoversized hole to be drilled. The detriments of an over-sized hole include reduced pullout force, increased ease of screws stripping in bone, and/or suboptimal fixation. Always irrigate during drilling.

– The slider is strictly for intraoperative use only; do notleave in-situ.

– Previous changes in the tempromandibular joint may affect surgical outcome.

Note: Use two screws on each side of the osteotomy toachieve stable fixation.
